3sixteenHere are the warp threads after their 4th dye. It's impossible to capture the entire system in one photo, but each continuous rope travels up and down on the rollers anywhere from 7-10 times in and out of indigo reservoirs. Indigo color depends on the type of cotton thread used, concentration of indigo, number of dips, and duration of oxidation in between dips. All of these factors can be controlled with incredible accuracy by Kuroki.

3sixteen@adamterry Yes, indigo oxidizes quickly but to achieve the deep, dark indigo that denim requires takes multiple dips and subsequent oxidation phases. I am not sure exactly how long each cycle is but if I'm not mistaken an entire morning was spent on one batch.

spyycanadaI love this behind-the-scenes look at denim production. This is exactly what we crave; an intimate knowledge of where our clothing comes from and how's it's created. Hi-5 everyone you meet for me :)
